SPOOL VALVE HYDRAULIC MOTORS GENERAL INFORMATION: Orbit motors convert hydraulic energy (pressure, oil flow) into mechanical energy (torque, speed). Hydraulic orbit motors operate on the principle of an internal gear (rotor) rotating within a fixed external gear (stator). The internal gear transmits the torque generated by the application of pressure from hydraulic oil fed into motor which is then delivered via the motor's output shaft. Orbit motors have high starting torque and constant output torque at wide speed range. DISTIBUTOR VALVE MLHM, MLHP, MLHR, MLHH, MLHPL, MLHRL, HP, HR, MLHRW, HW...
